Hi,

I have been using openCV FD(face detection) using Haar-like Cascade.

In the later versions of openCV while searching for faces the original image is re-sized w.r.t scale factor and feed to the cascade run at each window size, where as in the older versions the cascade rectangles and their weights are re-sized according to the window size and given for the cascade run without re-sizing original image.

May I know why exactly this is done in that way and what benefit do we get by searching in the latest version style?

Thanks Sandeep John.V
